AWS Certified Solutions Architect – Associate (SAA-C02) — Question 211
A company is planning to migrate a commercial off-the-shelf application from its on-premises data center to AWS. The software has a software licensing model using sockets and cores with predictable capacity and uptime requirements. The company wants to use its existing licenses, which were purchased earlier this year.
Which Amazon EC2 pricing option is the MOST cost-effective?
Answer options
- A. Dedicated Reserved Hosts
- B. Dedicated On-Demand Hosts
- C. Dedicated Reserved Instances
- D. Dedicated On-Demand Instances
Correct answer: A
Explanation
The correct answer is A, Dedicated Reserved Hosts, as they allow a company to use their existing licenses while providing a predictable cost structure for long-term usage. Options B and D, Dedicated On-Demand Hosts and Dedicated On-Demand Instances, can be more expensive due to their hourly pricing without commitment. Option C, Dedicated Reserved Instances, also does not provide the necessary licensing flexibility for socket and core-based licensing models.
